我的angular2应用程序遇到了很多麻烦。
我有一个非常简单的mvc应用程序(我使用的是asp.net)。
然而,我得到了一个 当我尝试在我的innertest组件中使用模板时,我的应用程序无法加载以下消息。
来自' @ angular / core&#39 ;;
的内部组件代码`import {Component}@Component({
selector: 'test',
template: require('./innerhome.component.html')
})
export class InnerTestComponent {
name = '';
}
`

我的systemjs.config.js文件是
(function (global) {
System.config({
paths: {
// псевдоним для пути к модулям
'npm:': 'node_modules/'
},
// указываем загрузчику System, где искать модули
map: {
// наше приложение будет находиться в папке app
app: 'app',
// пакеты angular

// пакеты, которые указывают загрузчику System, как загружать файлы без имени и расширения
packages: {
app: {
main: './main.js',
defaultExtension: 'js'
},
rxjs: {
defaultExtension: 'js'
}
}
});
})(本);
我不明白这个问题的原因。
请告知。

在装饰器中,您应该使用templateUrl而不是template。只要您引用的文件位于同一文件夹中,就应该只使用文件名,而不是路径:
templateUrl: 'innerhome.component.html'
每次指向组件装饰器中的另一个文件时,您还需要包括:
moduleId: module.id,
并确保在app.module声明中有InnerTestComponent。
整个组件将如下所示:
从@ angular / core';
导入{Component}@Component({
moduleId: module.id,
selector: 'test',
templateUrl: 'innerhome.component.html'
})
export class InnerTestComponent {
name = '';
}
